check_service_status

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It fails to mention whether the tool is read-only, requires authentication, has rate limits, or how it obtains status information. The output schema exists but the description adds no behavioral context beyond the basic purpose.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no wasted words, achieving conciseness. However, it could be restructured to include more detail about parameters or behavior without becoming verbose. It is appropriately front-loaded but lacks depth.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the presence of an output schema and the simplicity of the tool (2 required string params), the description is too brief. It does not provide enough context for an agent to understand how to fill parameters or what to expect, especially since parameter semantics are absent. The description should elaborate on what constitutes a 'service' and how to interpret the reasoning input.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage, meaning no parameter descriptions are present. The tool description does not explain what 'service' (e.g., service name, URL) or 'reasoning' (e.g., purpose of check) represent, leaving the agent to guess the semantic meaning of these required parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: checking if an API service or platform is experiencing issues. It uses a specific verb ('check') and resource ('API service or platform'), and it distinguishes itself from sibling tools like web_search, api_docs, etc., which focus on different tasks.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives or when not to use it. The description simply states what it does without contextualizing usage scenarios or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
